Start to Scratch

Start to Scratch

Every beginning is difficult, but you will see that at the end of this first Code class you have already got to know a lot of blocks!

You learn:

how to make a sprite move
to make a sprite say something
tomake a sprite make a sound
to repeat an action
to insert a background from the Scratch library as a playing field

You can get started with Scratch without creating an account. Do you want to save your projects and share them with others? Then you should create an account. You have three options:

Do you not have an account yet and do you need to create an account yourself? Then click on the button below and follow the steps.

ORIENTATE

Take a look at the example and consider the following questions:

What should I do?
What are the goals?
What are the expectations?
What can I already do?
What do I still have to discover?

View the steps at 'perform'. Then answer the following questions:

  • Which steps should I follow?
  • Which steps can I follow?
  • How much time do I need?
  • What tools do I need?

Do the steps one by one. Do you not remember how to do it? View the hints or download the solution.

STEP 1

Use the block 7. You will find this block in the 'move' category in the scripts. Double click a few times on the block. What is happening? The sprite (= the cat) moves to the right.

STEP 2

Paste the block 2a to the block  1.  What happens when you click on the sprite (= the cat)? The cat moves to the right.

STEP 3

Make when you click on the sprite, it also makes a sound. Choose the block 4 in the 'sound' category. Test out the different sounds by changing the number. Click on the white arrow and you will see the different options. What happens when you click on the sprite? The sprite moves to the right and makes a sound.

STEP 4

  • Paste the block  1  also under the block 4. Then change the number to -10. Click on the sprite. What is happening? The sprite will move to the right, make noise, and return to the left.
  • Make sure the sprite repeats this script. Use the block for this 6a. Drag this over the three blocks so that the mouth opens over the three blocks. Click on the sprite. What is happening? The sprite keeps repeating the script.

STEP 5

  • Add the block  8a from the 'Looks' category to the 'forever' script. Click on the sprite. What is happening? The sprite will say "Hello!" Through a speech bubble. for 2 seconds.
  • Click on the text in the box and change the text into a sentence or word of your choice.

STEP 6

Now we put the cat in a fun environment. Click "Choose a backdrop". Click on a background of your choice and then press 'OK'. What is happening? The background has changed to the one you just chose.

To see your blocks from just now, we have to go back to our sprite. This is important because we are now programming this sprite. Click at the bottom right on the icon of the sprite you want to program (= "have something done"). That's how you re-selected the sprite.

STEP 7

Experiment with the following blocks to teach your cat a better dance style.

12a

Look back at the project you just made. Ask yourself the following questions:

Does the program work as I expected? Why / why not?
What works well?
What works less well?
How can I approach it differently?
